WATER-CLOSET VALVE.

SPECIFICATION forming part of Letters Patent No. 590,240, datedSeptember 21, 1897.

I Application filed October 29, 1895. Serial No. 567,264. (No modeh) Toall whom it may concern.-

Be it known that I, JOSEPH H. SAVILL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inWater- Closet Valves; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in that class of water-closetvalves which are connected with the seat of the closet and are designedto be opened when said seat is pressed downwardly by the weight of aperson upon it, so as to admit water into the hopper or bowl of thecloset to flush the same; and its novelty and advantages will be fullyunderstood from the following description and claim, when taken inconnection with the an nexed drawings, in which Y Figure l is a verticalsection of a closet embodyin g myinvention, with parts in elevation.Fig. 2 is a vertical section illustrating my improved valve mechanism;and Fig. 3 is a detail section taken in the plane indicated by the linea: to of Fig. 2, with a portion broken away.

Referring by letter to said drawings, A indicates the hopper or bowl ofa water-closet, which may have the usual flush-horn a, an d may also, ifdesired, have the auxiliary horn b, fora purpose presently described.

B indicates the casing or frame which surrounds the bowl or hopper A,and is preferably provided in front of the bowl or hopper with the ledgeo. W

0 indicates the seat of the closet, which is connected in a hinged orany other suitable manner with the casing or frame B and is designed tobe normally held in the partlyraised position illustrated in Fig. 1, andD indicates the preferably upright casing of my improved valve. Thiscasin g D maybe made in any desired number of parts, but I prefer forthe sake of convenience in manufacturing and placing it in position toform it as better shown in Fig. 2 of the drawings-that is to say, of thelower section (I, which is designed to rest upon a suitable support orbase and be connected with a source of watersupply and is provided inits upper end with the screw-tapped opening e, the section f, which isscrew-tapped atits lower end to enter the opening 6 of section (Z and isprovided at-its lower end with the preferablybeveled valve-seat g and isalso preferably provided with the lateral branch h, designed to be connected by the pipe 2' with the horn b of the bowl, so as to enable waterthat collects in the casing above the valve to flow into the bowl, thesection j, which is screwed into the upper end of the section f, and thesection k, which is connected to the upper end of the section j and isprovided with the lateral branch Z, designed to be connected with'theflush-horn a of the bowl or hopper, as shown. This upper section k ofthe casing D is preferably flared upwardly and outwardly and providedwith the flange m at its upper edge, as shown, and it is designed tosupport the diaphragm E, of rubber or other suitable material, which isinterposed between it and a plate at, resting against the under side ofthe 'frame'ledge c, the casing-section k, the diaphragm E, and the platea being connected together by screws or bolts 1), and being connectedwith the frame-ledge c by bolts g, which preferably take throughelongated slots in the section it, diaphragm, and plate a, as shown inFig. 3.

As will be readily observed, the provision oftherelongated slots in thesection 70, diaphragm E, and plate it permits them being readilyconnected by bolts, as the slots of the several parts mentioned may bevery easily registered sufficiently to receive the bolts g.

F indicates the valve of my improvement. This valve F is designed andadapted to seat upwardly against the seat g in the casing D, and it isprovided on its under side with the reduced portion 9, designed toreceive the coiled spring G, which is interposed between the bottom ofthe casing D and the valve and is designed and adapted to return thevalve to and normally hold it tightly against its seat, so as to preventleakage.

it will be seen that when the weight of a person is imposed upon theseat it will be depressed, and in consequence the valve will be openedto permit water to flow into the bowl or hopper. When the weight isremoved from the seat, the valve will be raised against its seat and theseat 0 will also be raised and normally held in the position illustratedby the action of the spring G, before described.

As will be readily observed by reference to Figs. 1 and 2 of thedrawings, the diaphragm- E is increased in thickness at its center,where it is provided with the aperture to receive the valve rod or stem.The aperture 1 is of such a size as to very tightly receive the rod H,and in virtue of this and the elasticity and increased thickness of thediaphragm it will .be seen that the diaphragm will be frictionally heldto the rod H in a very secure manner and render it necessary to crowdthe rod into it and will move with the same. This, as will be readilyappreciated, prevents the hole if from being worn large by friction, and

consequently prolongs the usefulness of, the diaphragm and enables thesaid diaphragm, which is cheap and easy to place in position, toeifectually prevent the escape of water from the upper end of thevalve-casing and obviates the necessity of employing any packingwhatsoever, which is objectionable for the reason that it soon wears outand must be frequently replaced. It will also be observed that thisfrictional connection of the diaphragm E and rod H renders itunnecessary to employ nuts and similar devices for fixing thediaphragm,and therefore permit-s to frictional Wear or wear or strain ofany kind it will last almost if not quite as long as the other parts ofthe valve, which is a desideratuln.

I have shown an approved way of connecting the valve-casing with thehopper or bowl A, but I would have it understood that such casing may beconnected with the bowl or hopper in any manner suitable to the purposesof my invention.

Having described my invention, what I claim is- I In the waterclosetvalve described, .the combination of a bowl or hopper, averticallymovable seat 0, arranged above the bowl or ciprocatory rod orstem connected to the valve and extending upwardly and adapted'at itsupper end to impinge against or be connected with the seat, a springadapted to return the valve to and normally hold it against its seat,

and the diaphragm E, of rubber secured to g the valve-casing above theconnection of the same with the bowl and having the central, verticalaperture 25, receiving the valve rod or stem; the said aperture t, beingof such diameter or size in comparison to the diameter or size of therod or stem as to very tightly receive said rod and render it necessaryto crowd the rod or stem through it, whereby the diaphragm will be fixedto the rod or stem by frictional contact and the elasticity of thecrowded rubber so as to move with said rod in its up-and-down movements,substantially as and for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
